Type IIn supernovae (SNe IIn) are a heterogeneous class of supernovae. Neithertheir evolutionary status nor the origin of the tremendous mass loss from theirprogenitors are known. However, X-ray observations combined with multiwavelengthstudies can constrain the progenitor systems and lead to a wealth of informationabout the surrounding medium, the ejecta density and the structure of SNe IIn.Here we propose to do the {it XMM-Newton}-EPIC Spectroscopy of one Expanded VeryLarge Array (EVLA) and/or {it Swift}-XRT detected Type IIN supernova to unravelthe very nature of their environment.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
